DL-Mandelic acid is widely used as an antimicrobial agent, particularly in the treatment of urinary tract infections due to its ability to be excreted through the kidneys and act directly in the urinary tract. It functions as a urinary antiseptic by inhibiting the growth of bacteria such as *E. coli* and *Proteus* species. The compound is also employed in organic synthesis as a chiral building block for pharmaceuticals and fine chemicals. In skincare formulations, it serves as an alpha-hydroxy acid (AHA) that promotes exfoliation, improves skin texture, and helps treat acne and hyperpigmentation. Its mild nature compared to other AHAs makes it suitable for sensitive skin. Additionally, DL-mandelic acid is used in analytical chemistry for the separation and resolution of racemic mixtures, especially in chiral chromatography.
